All the countries started to dig, mine and burn the mother Earth for the resources to make weapons and continued until they ended up using everything and the mother Earth started to crumble as fragments into the thick and dark space as if it's not being held together as a sphere anymore, causing tsunami's and volcanic eruptions and many other weathering occasions.
The atmosphere became dense with all the polluted particles in air making it hard for humans to breathe and massive earthquakes which were never measured or recorded in the history ever before. It was the worst nightmare of the mankind ever.
